The war on drugs has just gone medieval. Yep, drug smugglers have apparently adopted the catapult–one of Gearlog’s own personal favorite siege weapons–to help transport marijuana over the Mexican-American border.

The National Guard spotted the device via video surveillance near the fence at the Arizona border. They located the three meter tall catapult on the back of a flatbed truck around 20 yards from the border.

Soldiers with the National Guard seized the vehicle, the device, and about 35 pounds of marijuana. According to the authorities, the device is capable of launching 4.4 pounds of marijuana at a time.
